Use the quick reference load charts or the main load charts to determine a suitable load bar size and series to suit your requirements. Eg- 255/1 or 325/2 etc...

Designate at the end of the code with an S if you require a Serrated surface, no designation will be assume a Plain surface.

Designate that you require Aluminium grating by referencing A=Aluminium grating

Designate the finish / treatment you require;

M= Mill finish

A= Anodised finish (specify to what thickness)

P= Powder coated finish

Specify the size of the area or panel sizes(s) for the grating you require along with the load bar direction (span)

Specify any additional information we need to know for example if there are cut outs or penetrations in the grating, do we need to split cut outs between panels for installation, is kick plate required, are the grates banded or cut to size only etc...
